SpaceX正在将Starlink卫星从2026年的550公里降至480公里,以减少2025年反常事件之后的碰撞风险。 SpaceX is lowering Starlink satellites from 550 km to 480 km in 2026 to reduce collision risks after a 2025 anomaly.

2026年,SpaceX将逐步将Starlink卫星从550公里降至480公里,以减少碰撞风险和改善空间安全。 In 2026, SpaceX will gradually lower Starlink satellites from 550 km to 480 km to reduce collision risks and improve space safety. 该移动是继2025年12月418公里的异常点之后进行的,该异常点涉及卫星通信损失和机载爆炸的可能性。 The move follows a December 2025 anomaly at 418 km, involving a satellite loss of communication and a possible onboard explosion. 降低轨道将星座置于一个不太拥挤的区域,碎片较少,卫星竞争较少,提高了脱轨效率和长期可持续性。 Lowering the orbit places the constellation in a less congested region with fewer debris and competing satellites, enhancing deorbiting efficiency and long-term sustainability. 随着Starlink网络在全球扩张,该变化支持SpaceX管理日益增长的空间交通的努力。 The change supports SpaceX’s efforts to manage growing space traffic as the Starlink network expands globally.
